WINDOW SHADE.

Application filed December 27, 1527.

The invention aims to provide a new and improved construction of window shade embodying a unique horizontally elongated casing to receive a shade roller, channel bars secured at their upper ends to said casing for disposition at the stiles of a window frame for the purpose ot receiving the edges of the shade and preventing entrance of light around the same, and novel means within said channel bars for guiding the shade.

\Vith the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being supplemented by the accompanying drawing.

Fig. 1 is an inner side elevation partly broken away and in section showing the invention applied to a window frame.

Fig. 2 is a vertical sectional view on an enlarged scale as indicated by line 2-2 of Fig. 1.

Fig. 3 is a fragmentary vertical section on line 33 of 2.

Figs. 4 and 5 are horizontal sectional views on the correspondingly numbered lines of Fig. 1.

The form of construction herein illus trated, will be rather specifically described, with the understanding that within the scope 30 of the invention as claimed, variations may be made.

The numeral 6 denotes a rectangular casing end, one of which is disposed at each end of a horizontally elongated shade roller casing 7 the inner side of each casing end 6 being provided with a bearing 8 for a shade roller 9 and with another bearing 10 for a shade-guiding roller 11. Two vertically disposed channel bars 12 have their upper ends 13 secured to the inner sides of the casing ends 6, at two lower corners of the latter, these bars being adapted for anchorage to the stiles of a window frame, by screws or the like 14. If desired, the lower ends of the bars 12 may be connected by a flat bar or strip 15 secured to the window sill by fasten ers 16. The other three corners of the casing ends 6 are received in and are secured to horizontal angle bars 17, said corners be-' 0'0 in preferably recessed at 18 for the reception of the bars 17, permitting the outer sides of these bars to be flush with the edges of the casing ends. These edges may if desired be widened by the provision of appropriate internal flanges 18. Casing front, back, top

and bottom members 192021-22 are secured to the end members 6 and to the angle bars 17, to complete the construction of the casing 7, and one longitudinal edge of the bottom member 22, extends no further than the channel bars 12, leaving a slot 23 in the bottom of the casing 7 in communication with the channels of the bars 12.

Vertical shade guiding wires 24 are provided, disposed one in the channel of each bar 12, the ends of these wires being anchored inv any desired manner. In the present showing, the lower ends of the wires 24 are se cured to eyes 25 carried by the bar 15, but in some instances, if this bar is not used, the eyes could be secured directly to the window sill. The upper ends of the wires 24 have been shown connected with turn buckles 26 which are in turn connected with one of the angle bars 17. Horizontal posts 27 are secured to one side of each channel bar 12 and are provided with notches 24 in their free ends which receive the wires 24 and hold the latter toward and parallel with the other sides of said channel bars. The shade 29 which is wound upon the roller 9, has its vertical edges received in the channels of the bars 12 and this shade is provided with transverse metal bars 30 suitably secured thereto, said bars 30 having projecting ends 31 which extend between the wires 28 and the adjacent sides of the channel bars 12. The extremities 32 of the projecting bar ends 31 are bent laterally toward the sides of the bars 12 which carry the posts 27. Thus, effective means are provided for guiding the shade 29, holding it in rather close proximity with one side of the bars or rails 12 and preventing removal of the shade edges from the channels of these bars, thus causing the shade and bars to co-operate in effectively preventing the entrance of light around the edges of said shade. The shade is guided into the space between the wires 24 and the adjacent sides of the channel bars 12, by means of the roller 11, as will be clear from Fig. 2.

The roller 9 preferably contains a spring 33 tending to rotate it in shade-rolling direction, and any desired means such as the cord 34 and pulley 35 may be employed for pulling the shade down. Also, any appropriate provision may be made to prevent rewinding of the shade on the roller until desired.

As excellent results may be obtained from the general construction herein disclosed, it may well be followed. However, attention is again invited to the fact that within the scope of the invention as claimed, variations may be made. Moreover, while the bars 12 are shown secured against the opposed sides of the window frame stiles, it is obvious that in some instances they may be secured against the inner or room side of the frame, in which instance, a casing 17 of one length spacing the bars 12 apart only one distance, would permit application of the structure to frames of various widths. It will be further understood that in some instances, the bars 12 and parts connected therewith might be secured against a wall instead of against a frame.

I claim 1. In a window shade, a pair of vertically disposed rectangular casing ends having shade roller-supporting bearings, two vertical channel bars secured at their upper ends to the inner sides of said casing ends at two lower corners thereof and adapted to receive edges of a shade, horizontal angle bars whose ends receive and are secured to the other corners of said casing ends; and easing front, back, top and bottom members secured to said casing ends and said angle bars, one edge of said bottom member terminating at said channel bars, leaving a shade-receiving slot.

2. In a window shade, a vertical channel bar for stationary mounting at a stile of a window frame, a vertical wire extending longitudinally in said channel bar and an chored at its ends, posts secured to one side and metal bars secured to said shade and having projecting ends slidably received between said wire and said other side of said channel bar, the extremities of said projecting' bar ends being bent toward said one side of said channel bar.

3. In a window shade, a pair of vertically disposed rectangular casing ends having shade roller supporting bearings, two vertical channel bars secured at their upper ends to the inner sides of said casing ends at two lower corners thereof and adapted to receive edges of a shade, horizontal angle bars whose ends receive and are secured to the other corners of said casing ends, casing front, back, top and bottom members secured to said casing ends and said angle bars, one edge of said bottom member terminating at said channel bars to leave a shade-receiving slot, a pair of turn buckles anchored to the angle bar which is disposed abovesaid channel bars, vertical wires within the channels of these bars and anchored at the lower ends of the latter, the upper ends of said wires 0 being secured to said turn buckles, horizontal posts within the channels of said channel bars and secured to one flange of the latter, the free ends of said posts being formed with seats receiving said vertical wires and holding the latter in close parallel relation with the other flanges of said channel bars, a spring roller supported by the above named bearings, a shade wound on said roller and extending downwardly through said slot with its edges disposed within the above named channels, and transverse metal bars secured to said shade and having their ends slidably received between said vertical wires and said other flanges of said channel bars.

In testimony whereof I have hereunto affixed my signature.
